Solar Cell

Solar Cell Practical Report 2011 Aim: To find the amount of power generated from a solar cell with a light bulb by using a multimeter. Hypothesis: The further you move the solar cell away from the light bulb the less power will be produced. Backup statement: I can support my hypothesis through my own given knowledge on power and electricity. I can comprehend the facts that, if the Light Bulb was generating a large amount of heat and light, the solar panel would be absorbing a majority of this energy if it were to be extremely close to the light bulb. Yet if the solar panel was to be drawn away, it would slowly lose that energy due to the distance of the panel. Variables:

-Dependant: Power output
-Independent: Distance of solar cell
-Consistent Variables: the electricity of the light bulb, solar cell, voltage, amps Materials:
•Ruler
•Multimeter
•Solar panel (cell)
•Light bulb
•Pencil/pen
•Paper
•Alligator clips
Method:1.Set up the equipment by plugging in the Light Bulb and attaching the Solar Panel to the Multimeter with the Alligator clips and the wires. 2.Begin by using a ruler to measure out the required distances for the practical 3.Switch on your multimeter and turn the switch clockwise until you reach 10 volts 4.Switch the light bulb on and start recording your measurements by measuring the amount of volts being produced by the Light Bulb. 5.Repeat this step, yet switch the multimeter to amps and re record your results, noting down the amount of amps being produced by the light bulb at each distance. 6.For further investigations, use a piece of paper for further results into the practical. This can be conducted by repeating the above steps with a sheet o paper 1 cm away from the solar panel. 7.Once finished, input your results into Microsoft Excel for your analysis of the results.

... and electricity is being generated and passed through the red wires at the end4.
Generating electricity through light comes about from exciting the electrons in a material when light is applied to it. The light displaces electrons in the material, most commonly a p-n junction semiconductor, which then leaves ‘free holes’ that allow electrons from other atoms to move into it. This resultant movement gives rise to electricity. The term photovoltaic comes from the Greek word ‘phos’ meaning light and ‘voltaic’ meaning electric. The materials presently used for photovoltaic’s include monocrystalline silicon, polycrystalline silicon, cadmium telluride and copper indium selenide/sulfide6. This is an example of a common use of solar/ photovoltaic cells.
Uses of Piezoelectricity
Some common uses of piezoelectricity include;
Quartz crystals in watches
Cigarette lighters
X-ray shutters
Inkjet printers.
The Boeing 777 uses piezoelectric ceramic material within its ultrasonic fuel tank probes. The ultrasonic transducers are installed at a variety of locations in each fuel tank. A pulsed electric field is applied to the material, which then responds by oscillating. The resulting sound waves are reflected off the surface of the fuel and picked up by the transducer. A digital signal processor interprets the ‘time of flight’ measurement of the sound waves in order to continually indicate the amount of fuel present 2....

...Photovoltaic cells are solid state devices that convert light directly into electricity. Photovoltaic literally means "light electricity." These devices can be commonly found providing power for small scale devices such as calculators, watches, and small radios. However, they are not limited to small scale systems. They are also used to power satellites, communications equipment, houses and many other things, especially in remote locations where a power grid is not readily available. In isolated locations the only power attainable comes from the sun. The sun shines approximately 1000 watts of energy per square meter of the planets surface, which if harnessed could power any city.
The commercial development of the photovoltaic cell took more then a hundred years to begin. A french physicist Edmond Becquerel first described the photovoltaic effect in 1839. At the age of 19 Becquerel found that certain materials when exposed to light produced small measurable currents. Henrich Hertz also studied the effect in solids in the 1870's and he managed to produce photoelectric cells with an efficiency of about 1%. In the 1940's the new Czochralski process made generating highly pure crystalline silicon possible and furthermore made commercializing photovoltaic cells an option. Development really started however, in 1954 when Bell Laboratories used the Czochralski process to produce a 4% efficient crystalline silicon...

...﻿Which is the more viable energy source for Australia’s energy and needs, Wind or Solar? This is a common debatable topic within the Federal Government of Australia. Debating which specific form of energy should be invested heavily in, in hope that carbon emissions and the use of coal will be reduced in the future (Clean Line, 2013). It is believed that the dominance of coal will be challenged by renewable energy e.g. Wind and Solar. Renewable energy is fast, clean, affordable, efficient, reliable and ultimately infinite in that both Wind and Solar are an endless effective energy source. This form of energy releases no carbon emissions thus resulting in a cleaner environment, that also helps create jobs and stimulate local economies (Clean Line, 2013). Throughout this investigation the social and environmental relevance in relation to geology will be highlighted as well as which Alternative Energy of Wind and Solar will be a more viable option to be heavily invested in as well as relating it to ‘Australia’s energy consumption and/or needs’. Specifically for this investigation we will be determine both advantages and disadvantages of Solar Panels and Wind Turbines these are the most popular resource and infrastructure that relate to Wind and Solar energy. This process will decrease the possibility of biasness throughout this investigation.

Solar Energy: The Energy of the Future
Our Earth's resorvoir of resources seem to be limitless, but with the exponential growth of the human population; the need for efficient alternative energy sources is becoming urgent. Therefore, research companies and individuals are focusing on creating new energy systems. Fossil fuels are are depleting and becoming more difficult to obtain. The earth will face an energy crisis in the near future if humans are not careful with their consumption. To avoid this disaster it is vital for us to utilize alternative sources of energy to its full potential. Widely used fossil fuels like coal, oil, and petroleum are very harmful to the environment. The earth is warming up, the climate is changing, and the ozone layer is gradually thinning, largely due to the effects of fossil fuels. Although fossil fuels are currently the main source of energy; solar energy may one day replace fossil fuels in the future.
Fossil fuels do not self-sustain naturally at a fast enough pace, to match society's high energy demands. Resources are diminishing quicker than the Earth can replenish them. Unlike renewable energy sources, most of which are converted to power cleanly, the conversion of fossil fuels to energy harms the environment. Processing fossil fuels emit harmful greenhouse gases, primarily carbon dioxide, methane, and nitrous oxide, into the air. Thus, polluting the air, creating respiratory health issues...

What is Photosynthesis?
Photosynthesis simply means the conversion of light energy into chemical energy by living organisms. In photosynthesis, the raw materials are water and carbon dioxide. Energy is taken from sunlight and the end products give out glucose and oxygen. It is the most important, naturally occurring process of life because all living organisms depend on it. In this process, plants use solar energy to produce sugar. then during cellular respiration, these sugars are converted into ATP. ATP is the fuel that is used by all living organisms. The conversion of the unused sunlight energy into usable chemical energy is associated with the actions of the green pigment chlorophyll. In this process, water is used and oxygen is released that we absolutely need to stay alive. we can write the over all reaction of this process as:
6 Water molecule’s + 6 CO2 molecule’s + light → 1 Glucose molecule + 6 oxygen molecule’s
How is solar energy transformed into electrical energy?
Solar energy is what keeps us all alive. The earths temperature is retained from the light and heat taken from the sun. how easily solar energy is converted into light energy is important. The Photovoltaic...
